#162 LU factorization of the G Matrix failed New issue created by peijunh Hello. I want to thank you for the update on common_pdn.tcl. After the update of @Manarabdelaty , I run my design with macro and get the error in the following figure. My macro includes a sensor and sky130_sram_4kbyte_1rw1r_32x1024_8. sensor use VDD and VSS as power pin and sram use vccd1 and vssd1 as its power pin. So I change the "set macro" in common_pdn.tcl as follows.

set macro {

orient {R0 R180 MX MY R90 R270 MXR90 MYR90}

power_pins "vccd1 VPWR VDD"

ground_pins "vssd1 VGND VSS"

blockages "li1 met1 met2 met3 met4"

straps {

}

Could you share suggestion and advice on this error? Thanks! RTimothyEdwards/open_pdks
